A New Jersey man who fatally shot his wife, another man and an infant before killing himself Monday night left a letter detailing his murderous intentions.

Hudson County Prosecutor Edward DeFazio says investigators found the letter in Adepso Collado's car Wednesday during a routine search. It was a couple of pages long and was found between the car's console and the driver's seat.

According to the note, Collado may have also planned to kill his two daughters, who escaped injury.

"I think you could infer that (his daughters) were at risk," said Hudson County Prosecutor Edward DeFazio. "It isn't stated but I think that they were at risk... It might have been that he was in fact distracted by the arrival of police."

The Star-Ledger reports Collado went downstairs in the home after killing his wife, and had a conversation with his young daughters.

He showed the weapon he used to kill their mother and apparently asked his children, "Do you want to go to heaven or go to hell?," The Star-Ledger reports, citing accounts from two close friends of Kenia Collado.

The oldest daughter told her father she didn't want to go anywhere. As police entered the home, Adepso shot himself, The Star-Ledger reported.

DeFazio says the letter makes it clear the reason for the attack was the Collado's failed marriage.
